Hi Josh,
Do you have a tutorial on how to configure a VPN with NAT hide before VPN. I need to create a tunnel betwen two companies but one of them works with public adresses and do not accept rfc 1819 addresses.
Thanks in advance

Hi Josh,

you gave a cisco amateur an very nice ‘guide’ for a basic understanding in setting up a VPN and i’m proud to say i succeeded in my more ‘complex’ environment setup.

Thank you !

router1 and router2 were connected through E1

Josh,

I completely understand, I can only imagine how busy you must be with request such as mine on this site, it was worth a shot. Thanks for the links though, that was really considerate of you, those were really very helpful.

Best regards,

george

George,

I honestly do not have time to do a tutorial on the nat/pat on a stick.

Hi Josh,

I return to this page quite regularly to see if you found the time, or even the inclination to post something on the NAT/PAT on a stick we discussed some time ago. Josh, please, post a demo of this type of config?

Hi Josh,

Thanks for replying. From what i’ve gathered, nat on a stick involves the use of a router with a single physical ethernet interface and utilizes a virtual loopback interface to make up for the lack of another physical ethernet interface. The router is connected to a hub, as is the host PC or switch that connects host PCs. I have also heard of your description using a switch to connect to the single physical interface using VLANs to nat the inside to the outside, but I am even more confused about this process as far as how to configure nat for it to work. Maybe this is another post you can/should provide. I’m sure there are a lot of Cisco newbies like nyself with routers with single ethernet interfaces that would just LOVE TO HAVE access to configs like these to get online using their gear.

Thanks again Josh,

George
